LUBRIOATING DEVICE FOR CAR-AXLE JOURNALS.

SPECIFICATION formingpart of Letters Patent N0. 752,162, dated February 16, 1904.

Application filed April 28, 1903.

To all whom it may concern.-

Be it known that we, FRANK BENJAMIN HAR- RISON and LACEY YEA vVrLLnuvr's, citizens of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invent-' ed new and useful Improvements in Lubricating Devices for Oar-Axle Journals, of which the following is a specification.

The object of our inventionis the provision of a suitable lubricating device for journals which are housed in boxeswhich have a curved surface in the bottom thereof or are concave in cross-section at the bottom, said deviceto be so constructed and designed that it will be economical in the use of lubricating material, eflicient in operation, cheap in first cost and in maintenance, which shall preferably be so shaped that it can be inserted and withdrawn. through the opening in the box only after the box has been raised, the brass and wedge removed, and the box again lowered upon the journal, and which shall possess desirable features and characteristics constituting it a superior means for furnishing perfect lubrication.

Our invention consists in a lubricating device embracing a spring-supported pan curved in cross-section combined with a journal-box having a concave interior surface at the bottom thereof.

It further consists in certain novelties of construction and combinations of parts, hereinafter set forth and claimed.

The accompanying drawings illustrate an example of the physical embodiment of the invention constructed according to the best mode we have so far devised for the practicai application of the principle.

Figure 1 is a longitudinal section of ajournal-box, showing the concave bottom thereof,

the concave pan, and the journal in their rel- A ative positions. Fig. 2 is a top plan View of the pan. Fig. 3 is a bottom plan view of the pan. Fig. 1 is a side view of the pan. Fig.

- 5 is a cross-sectional View of the pan, the skeleton base, and the spring. Fig. 6 is a bottom plan view of the curved skeleton base detached. Fig. 7 is a view of the spring in perspective.

Serial No. 154,717. on model.)

1 designates the journal-box; 2, the opening in the end; 3, the concave bottom of thebox, shown curved by the shading lines; 4, the journal; 5, the pan, preferably made of sheet metal struck up by dies to the desired shape; 6,'the rear end of the pan, having a curved edge to conform to the curve of the journal; 7, a waste-retainingdevice Fl-shaped in crosssection and fitting or lapping over the rear curved wall of the pan, as shown in Figs. 1

and 5; 8, a spring rod or wire secured to the edge of the retainer in any suitable way; 9, the ends of the spring wire or rod fastened to the pan and which spring forces the retainer or guardagainst the lower curved surface of the journal, closing the space between the edge of the pan and the journal, thus preventing the waste which holds the lubricant working over the rear edge of the pan; 10, the cup-shaped front end of the pan into which the lubricant is poured; 11, the flattened end of the pan, which enables the same to be withdrawn and inserted through the open ing of the box with facility; 12 12., the side walls or edges of the pan; 13, seats for the upper parts of the post-housings; 14;, the bottom of the pamcurved in cross-section; 15 15, recesses in the edges of the pan; 16, seatsfor the lower parts of the post-housings; 17, an X-shaped recess in the bottom of the pan; 18,

the skeleton base, curved in cross-section; 19, the sides of the skeleton which fit within the recesses 15 when the spring is collapsed; 20, the X-shaped portion of the skeleton which fits the X-shaped recess in the bottom of the pan when the base is forced into contact with the pan; 21, holes in the corners of the skeleton; 22, headed posts secured to the base, the heads moving freely within the housings and preventing the separation of the base from the pan; 23, the upper parts of the post-housings; 24, the lower parts of the housings, which parts are secured to the pan in any suitable Way adjacent holes in the pan through which. the posts pass; 25, a spring located between the skeleton base and the bottom of the pan and adapted to collapse or be compressed into the X-shaLped recess in the bottom of the pan, and 26 represents the compressible arms that we have provided a lubricating device of the spring which force the pan and waste therein into frictional contact with the bottom surface of the journal.

To withdraw the lubricator or to introduce it into the box in the preferable combination, the box is raised, the brass and Wedge removed, and the box lowered, thus enlarging the normal open space between the end of the journal and the opening in the box, the base compressed so that it will lie in contact with the bottom of the pan, when its dimensions will be such that it may be passed through the open space at the end of the journal and the opening in the end of the box.

. It will be observed that when the skeleton base is pressed to the bottom of the pan the skeleton fits within the recesses in the bottom and sides of the pan and that the posts project upwardly into the housings, that the pan has ample capacity for lubricating material, and that the retainer at the rear end of the pan will prevent the waste working over the edge thereof and conveying the lubricant to the bottom of the journal-box.

From the foregoing description it is obvious especially adapted for use with a journal-box having a curved or concave bottom.

What We claim as new, and desire to secure by Letters Patent, is-

1. The combination in a lubricatingdevice, of a pan, a base, posts uniting the base and pan, and a spring independent of the posts and located between the base and the bottom of the pan,

'2. The combination in a lubricating device, of a pan provided with recesses in its sides and bottom, a skeleton base, and a spring, said recesses adapted to receive the spring and base when the base is pressed to the bottom of the pan. V

3. The combination in a lubricating device,

of a pan, a base, posts uniting the pan and base and secured to the corners of the base, housings for the ends of the posts, and a spring located between the central'portion of the base and the bottom surface of the pan.

4:. The combination in a lubricating device, of a pan with recesses in its bottom, a skeleton base, a spring adapted to be compressed into the recesses of the pan, and means for guiding the base relative to the pan.

5. A lubricating device comprising the pan 5, base 18, spring 25, and posts 22, the said spring being independent of the posts and located between the bottom surface of the pan and the top surface of the base.

6. The combination with a lubricating-pa of a F'l-shaped guard embracing the rear wall of the pan, and a spring, for the purpose set forth.

7. The combination with a lubricating-pan, of a spring for pressing the same to the journal; a waste-retainer at the rear wall of the pan, and a spring in connection with said wasteretainer and forcing the retaineragainst the journal.

8. The combination with a journal and concave journal-box, of a pan having a recessed concavo-convex bottom; a base concavo-convex in cross-section; means for holding the base in line with the pan; and a spring mechanism for forcing the pan to the journal; said base being adapted to be pressed .into' the recesses within the bottom of the pan so that the pan and base may be Withdrawn from the box through the opening in the end thereof. v

In testimony whereof we aflix our signatures in presence of two witnesses. v p
